What causes a 500 error when making a fetch request in Nuxt.js?

Several factors can lead to a 500 error during a Nuxt.js fetch request. Common causes include: 1) Incorrect API endpoint URLs. 2) Issues with the API server (e.g., server downtime, API errors). 3) Authentication problems (e.g., invalid API keys, expired tokens). 4) Network connectivity problems between your Nuxt app and the API server. 5) Issues with the data being sent in the request (e.g., incorrect data format). 6) Server-side errors in your Nuxt API routes.
